CmCULAE  FOR  THE  INFORMATION  OF  PERSONS  DESIRING  TO  ENTER 
THE  NAVY  AS  ACTING  ENSIGNS  FOR  ENGINEERING  DUTY. 


An  act  of  Congress  approved  August  29,  1916,  authorizes  the  appointment  of  30 
acting  ensigns,  annually,  as  follows: 

' '  That  the  Secretary  of  the  Navj^  is  hereby  authorized  to  appoint  annually  in  the 
line  of  the  Navy  for  a  period  of  ten  years  following  the  passage  of  this  act,  in  the  order 
of  merit  determined  by  such  competitive  examination  as  he  may  prescribe,  thirty 
acting  ensigns  for  the  performance  of  engineering  duties  only.  Persons  so  appointed 
must  have  received  a  degree  of  mechanical  or  electrical  engineer  from  a  college  or 
university  of  high  standing  or  be  graduates  of  technical  schools  approved  by  the  Sec- 
retary of  the  Navy,  must  have  been  found  physically  qualified  by  a  board  of  medical 
officers  of  the  Navy  for  the  performance  of  the  duties  required,  and  must  at  the  time 
of  appointment  be  not  less  than  twenty  nor  more  than  twenty -six  years  of  age.  Such 
appointments  shall  be  for  a  probationary  period  of  three  years,  and  may  be  revoked 
at  any  time  by  the  Secretary  of  the  Navy. 

"Such  acting  ensigns  shall,  upon  the  completion  of  the  probationary  period  of  three 
years,  of  which  two  years  shall  have  been  spent  on  board  cruising  vessels  and  one  year 
pursuing  a  course  of  instruction  at  the  Naval  Academy  prescribed  by  the  Secretary 
of  the  Navy,  be  commissioned  in  the  grade  of  lieutenant  of  the  junior  grade  after  sat- 
isfactorily passing  such  examination  as  may  be  prescribed  by  the  Secretary  of  the 
Navy,  and  having  been  recommended  for  promotion  by  the  examining  board  and 
found  physically  qualified  by  a  board  of  medical  officers  of  the  Navy. 

"Such  officers  shall  thereafter  be  required  to  perform  engineering  duties  only,  and 
shall  be  eligible  for  advancement  to  the  higher  grades  in  the  manner  herein  pro"\dded 
for  line  officers  assigned  to  engineering  duty  only." 

APPOINTMENT. 

A  candidate  for  appointment  as  acting  ensign  for  engineering  duty  must,  at  the 
time  of  appointment,  be  a  citizen  of  the  United  States,  not  less  than  20  nor  more  than 
26  years  of  age,  a  candidate  who  has  passed  his  twenty-sixth  birthday  not  being 
eligible.  Attention  is  particularly  invited  to  the  italicized  portion  of  the  preceding 
sentence.  Although  a  candidate  may  successfully  pass  the  professional  and  physical 
examination  his  appointment  can  not  be  made  unless  he  i.s  within  the  prescribed 
age  limit  at  the  time  he  accepts  an  appointment  that  may  be  tendered  by  the  depart- 
ment after  passing  all  examinations.  The  age  limit  is  prescribed  l)y  law  and  the 
Navy  Department  has  no  discretion  in  the  matter  of  wai^ving  same. 

Therefore,  no  person  will  be  permitted  to  appear  who  will  pass  his  twenty-sixth 
birthday  within  two  months  after  the  date  set  for  the  examination.  This  is  done  in 
order  to  prevent  candidates  from  going  to  the  trouble  and  expense  of  appearing  for 
examination  when  it  is  certain  that  they  can  not  be  examined,  ha^•e  their  papers 
marked  by  the  local  board  in  Washington,  and  their  appointments  issued  and  accepted 
before  reaching  the  statutory  age  limit  of  26.
